where can I change the Nextcloud below?

[chiyi4488]

Excuse me, if I open the maintenance mode, where can I change the Nextcloud below ( and ''keep your data'')?

[nextcloud-bot]

GitMate.io thinks possibly related issues are #5169 (nextcloud 12 changing emails on users?), #7752 (NextCloud Instance Down), #104 (NextCloud / OwnCloud), #5405 (Nextcloud / direct_menu), and #4368 (nextcloud client crash after changing server adress).

No, I mean, if I turn on maintenance mode, the text inside doesn't become the name I wrote in the theme, I want to change it (direct file change)

This is a know limitation:

The the app data and the theming app is not available. Nevertheless there is the idea of a plain maintenance mode page: #5789

Thus closing as duplicate of #5789 (see also #9069)

[chiyi4488]

Okay, but where is the maintenance mode html file? I want to modify it directly.

https://github.com/nextcloud/server/blob/master/core/templates/update.user.php

And the normal layout is at https://github.com/nextcloud/server/blob/master/core/templates/layout.guest.php

[chiyi4488]

Um.....I read the file, but I didn't see any strings that would allow me to modify Nextcloud and keep your data... (sorry, poor understanding)

[chiyi4488]

Or do I have to go to themes folder to make changes?

The "Keep your data ..." is the slogan in the layout file. Best is to overwrite that file in a theme. For themes read the docs, but be aware, that it very likely need to be updated on every major version upgrade to not break the system. Thus we tend to avoid using themes, because they have a high maintenance cost and high risk of breakage.
